Percent Reduction after Drawing Solution

Follow our step by step solution on how to calculate Percent Reduction after Drawing?

FIRST Step Consider the formula

PR % = 100 \cdot (1 - \frac{d s}{D b})

Next Step Substitute values of Variables

∴

PR % = 100 \cdot (1 - \frac{80mm}{84.2mm})

Next Step Convert Units

∴

PR % = 100 \cdot (1 - \frac{0.08m}{0.0842m})

Next Step Prepare to Evaluate

∴

PR % = 100 \cdot (1 - \frac{0.08}{0.0842})

Next Step Evaluate

∴

PR % = 4.98812351543942

LAST Step Rounding Answer

∴

PR % = 4.9881
